本発明は、電子写真特に乾式PPC用の転写紙に関する
。TECHNICAL FIELD The present invention relates to transfer paper for electrophotography, particularly dry PPC.
従来技術

った。Conventional electrophotographic transfer paper tends to curl due to the shrinkage force of the cellulose fibers due to water evaporation due to the heat of the heater, and due to the hardening caused by the passage between the fixing roll and the pressure roll.
There were problems related to errors in the copying machine, uneven copies, sorter errors, and poor running performance when the number of sheets stored in the sorter decreased.
そこでコピ一作業性(走行性)の安定を計るためにカー
ル特に加熱時におけるカールに対する安定性が没水され
、種々の提×かなされている。Therefore, in order to stabilize the copying workability (travelability), various proposals have been made to improve stability against curling, especially during heating.
例えば、緊度、含水分率、電気抵抗などを一定範囲とす

未だ充分とはいえない。Such transfer paper has almost no curling after copying in areas other than the edges, which correspond to most of the IJ direction, and has satisfactory running performance. ear (50cm on one side, about 1cm on both ears)
Transfer paper using a portion corresponding to 0.00 cm) has a large curl after copying, and there are cases where diagonal curl occurs in which the diagonal corners of the transfer paper are larger than other corners. However, it is still not sufficient to meet various demands such as increasing the copying speed, double-sided copying, and the use of a sorter.
目的
熱定首部をもつ電子写真装置(乾式RPC複写機)に使

減少などの欠点の改良された転写紙を得ることである。Purpose: When used in an electrophotographic device (dry type RPC copying machine) with a heat-fixed neck, the curl of the copy paper is small,
To obtain a transfer paper which is improved in drawbacks such as uneven copies, sorter jam, and reduction in the number of sheets stored in a sorter.
構成
本発明は、下記(インないし3\)の特性を漏えたこと

められることが多く、特にこのようなものは抄造原紙の
耳部に多いことが判った。As a result of various researches, it has been found that in copying machines and sorters, curls (diagonal curls) in which the corners of the paper are raised, leading to paper jams, are often found. It was found that such substances were especially common in the edges of papermaking base paper.

づる。Therefore, in the present invention, it has been discovered that in order to mainly prevent and cover such curling, it is sufficient to add the above-mentioned requirements a'1 (a) to 3\) by -1. Each requirement is explained below.
(インについて
これは僅力向に配向している繊維と縦方向に配向してい

となり、走行↑」不良が発生Jる。また、横剛麿が低下
し、特に高湿時走行不良を発生する。(About In, this is an index that shows the ratio of fibers oriented in the slight force direction and fibers oriented in the machine direction. Culm fibers close to 1 are oriented in the same direction and are oriented in the J3 direction, and conversely in the O direction.) The closer it is, the more fibers are aligned in the vertical direction.If Y/T is less than 0.4, there are many m strings oriented in the vertical direction, the vertical curl becomes more than iomm, and a running ↑" defect occurs. In addition, the lateral stiffness decreases, causing poor running, especially in high humidity.
Y / 1−が大きいと、例えば0.6以上では、通常

紙特性としては(CI)の条件を満足すればY/Tが大
きくとも差支えない。When Y/1- is large, for example 0.6 or more, there is a high probability that the fibers will be oriented diagonally in the normal papermaking process, and there is a high risk of diagonal curling; If the conditions of CI) are satisfied, there is no problem even if Y/T is large.

This shows that the vA fiber orientation is not symmetrical, that is, it is biased to the left or right, and the fibers are aligned diagonally when synthesized.Specifically, the former is 1, Okg If the latter is larger than 1.25, the curl after copying will be 10 mm or more, resulting in poor runnability.

From this point of view, the permissible basis weight variation is the width of the paper. Direction 5C
